To connect the chassis to ground, use a ring-type terminal (ring cable lug) which is suitable for a M4 screw and connect
it to the chassis ground terminal on top of the unit.
Instructions:
a) The external circuitry of all terminals must meet the safety requirements stipulated by IEC/EN/UL 60950-1: SELV.
b) Use appropriate copper cables that are designed for minimum operating temperatures of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C and
90°C for ambient up to 70°C minimum.
c) Follow national installation codes and installation regulations!
d) Ensure that all strands of a stranded wire enter the terminal connection!
e) Screws of unused terminal compartments should be securely tightened.
f) Ferrules
are allowed.
g) Do not connect or disconnect the wires from the terminals below -25°C (-13°F).
